DESCRIPTION OF THE PREFERRED EMBODIMENTS

In discussing a preferred embodiment of the invention, illustrated in drawing FIGS. 1-10, specific terminology will be resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms or materials,and it is to be understood that each specific term/material includes all technical equivalents which operate in a similar manner to accomplish a similar purpose. The invention is to be used with two twin or single beds, 20, 40 which are pushed together. The first bed 20 typically comprises a first framework 22, a first box springs 24 and a first mattress 26. The first bed 20 typically has a first side 28, a second side 30, a first end 32, a second end 34, a first top 36 and a first bottom 38.

The second bed 40 typically also comprises a second framework 42, a second box springs 44 and a second mattress 46. The second bed 40 typically has a third side 48, a fourth side 50, a third end 52 and a fourth end 54, a second top 56 and asecond bottom 58.

To join the first bed 20 and the second bed 40 together to form a larger bed 60, the second side 30 of the first bed 20 and the third side 48 of the second bed 40 are placed adjacent to each other.

As shown in FIG. 1, a seam protector 10 is placed across the seam 62 formed by the second side 30 of the first bed 20 and the third side 48 of the second bed 40. The seam protector 10 extends the length of the first and second beds 20, 40, andfurther extends across the first and third ends 32, 52 and the second and fourth ends 34, 54 of the first and second mattresses 26, 46. In an alternate embodiment, the seam protector 10 farther extends near the first and third ends 32, 52 and the secondand fourth ends 34, 54 of the first and second box springs 24, 44.

The seam protector 10 is preferably made of a comfortable, cushioning material, such as a sherpa or lambs wool, but can be constructed of any soft material found in the market place that is washable and does not create a thick seam. The edges ofthe seam protector 10 are preferably sewn to prevent fraying.

As best shown in FIG. 5, an added cushioning material 11 may be attached to the underside of the seam protector 10. Alternately, the seam protector 10 may fold over the cushioning material 11, to enclose the cushioning material 11 therebetween. A pocket may also be formed in the seam protector to receive the cushioning material 11 therein. The cushioning material 11 is located so that it covers at least a portion of the first and second top portions 36, 56 of the first and second beds 20, 40along the mattress seam 62. The cushioning material 11 preferably extends the full length of the second and third sides 30, 48 of the first and second beds 20, 40 along the mattress seam 62.

The cushioning material 11 is preferably made of Dacron, foam or similar material typically used for padding. The seam protector 10 may be adapted for use with or without cushioning material 11, to suit manufacturing and user preference. Alternately, the cushioning material 11 may also be a flexible strip of material, such as a thin, flat plastic. The cushioning material 11 may be sized to cover any mattress welting (not shown), even to cover the entire first and second top portions 36,56 of the first and second beds 20, 40. The cushioning material 11 may be rectangular in shape, or molded in any suitable shape, such as a V-shaped foam material. The seam protector may be cut with V-shaped or S-shaped edges to suit manufacturingpreference.

The first and second mattress straps 12a and 18a may be made of a pliable, durable, washable material, which does not substantially stretch or give way when normal man-made pressure is applied. The first mattress strap 12a is sown, or otherwisesecured by any known means, to one end of the seam protector 10.

The second mattress strap 18a is sown, or otherwise secured by any known means, to the opposite end of the seam protector 10. Preferably, the first and second mattress straps 12a, 18a are secured to opposing ends of the seam protector at rightangles, with equal lengths extending on each side of the seam protector 10.

In an alternate embodiment, the seam protector 10 extends at least partially along the first and second ends 32, 34 and the third and fourth ends 52, 54 of the first and second beds 20, 40. Third and fourth box springs straps 12b, 18b aresecured in spaced relation from the first and second mattress straps 12a and 18a. The first and second mattress straps 12a, 18a are positioned to extend about the middle portion of the sides of the first and second mattresses 26, 46.

The first and second box springs 24, 44 are secured together with the third and fourth box springs straps 12b, 18b positioned about the middle portion of the sides of the first and second box springs 24, 44. The first and second mattress straps12a, 18a are each of a length suitable to extend across one end of the first and second beds 20, 40, and further to extend at least half way along the first side 28 of the first mattress 26, and at least halfway along the fourth side 50 of the secondmattress 46. Preferably, the first and second mattress straps 12a, 18a encircle the first and second mattresses 26, 46 and extend at least three inches to 12 inches further, for ease of releasably securing the first and second mattress straps 12a, 18atogether about the first and second mattresses 26, 46 with a suitable releasable fastening means 14a, 14b.

The third and fourth box springs straps 12b, 18b are of a length suitable to extend across one end of the first and second box springs 24, 44, and farther to extend at least half way along the first side 28 of the first box springs 24, and atleast halfway along the fourth side 50 of the second box springs 44. Preferably the third and fourth box springs strap 12b, 18b encircles the first and second box springs 24, 44, and extends at least three to twelve inches further for ease of releasablysecuring the third and fourth box springs strap 12b, 18b together about the first and second box springs 24, 44 with a suitable releasable fastening means 14c, 14d. The length of extension of the straps 12a and 12b and 18a and 18b would depend on whattype of fastening means 14a-d is utilized.

The releasable fastening means 14 may be in the form of a buckle as shown in FIG. 3A, or may be any known releasable fastening means 14, such as a ring shown in FIG. 3B, or a hook and loop fastening means. There are also various types ofmale/female buckling or connecting devices sold at fabric and upholstery stores, such as buttons, snaps, hooks, etc. which may also be used as the fastening means 14 a-d. While FIG. 5 shows both mattress straps 12a, 18a, and box springs straps 12b, 18b,it is noted that only one set of straps 12a, 18a are needed in a preferred embodiment.

The fastening means 14 is provided to adjustably position the straps 12a, 18a about the sides of adjacent first and second mattress 26, 46, and to releasably secure the straps 12a, 18a about the first and second mattresses 26, 46. Likewise,additional fastening means 14 may be used to position the straps 12b, 18b about the sides of adjacent first and second box springs 24, 44, and to releasably secure the straps 12b, 18b about the first and second box springs 24, 44.

Any known binding means 16, such as hook and loop fasteners, snaps, buttons, loops, and other known commercially available releasable fastening devices may be used to secure the loose ends of the straps 12a, 12b, 18a, 18b so they do not hangloose.

Where additional length is desired, to convert two adjacent beds 20, 40 to the length of a king sized bed, a bolster 70 may be provided for releasable securement to the first end 32, 52, or second end 34, 54 of the adjacent beds 20, 40. Thebolster 70 may be secured with the mattress straps 12a, 18a, as shown in FIG. 6. When a bolster 70 is used, the seam protector will be extended by at least five inches, and the length of the mattress straps 12a or 18a will also be extended accordingly. The bolster 70 may be sized to extend the width of the first and second beds 20, 40, or may alternately be a separate bolster 70 for each of the first and second beds 20, 40.

The bolster 70 is preferably made of a high density foam, having an indentation along one end, sized to receive the mattress straps 12a or 18a at about the midpoint of the bolster 70, with the indentation deep enough to keep the straps frommoving, as shown in FIG. 6. The bolster 70 could be enclosed in material such as nylon, or other suitable material which can be cleaned. Alternately, the bolster 70 may be held in place by the straps 12a or 18a with a suitable binding material 17, suchas hook and loop fasteners, snaps, etc. The bolster 70 may include an angled bottom, which provides added support.

This invention is for the purpose of combining two adjacent twin or single mattresses 20, 40 without the fear that the mattresses will separate during use. The seam protector 10 is placed over the seam formed by the two mattresses pushedtogether, with the overhang falling equally over both ends 32, 34 and 52, 54. The purpose of the seam protector 10 is to cover the mattress seam and welting for better sleeping comfort. The seam protector 10 also serves to fill some of the slopebetween the two mattresses 20, 40. The seam protector 10 further serves to position the straps 12a, 18a at approximately the midpoint of the height of the first and second mattresses 26, 46.

Where box springs straps 12b and 18b are used, straps 12b and 18b are positioned at approximately the midpoint of the height of the first and second box springs 24, 44. Were the straps not held in position by the seam protector 10, it would bevery cumbersome and difficult to position the straps 12a, 12b and 18a, 18b around an object as large as two mattresses 26.46, or box springs 24, 44, particularly if one person were doing it alone.

The straps 12a, 18a are preferably releasably secured by the fastening means 14, one side at a time. After releasably securing the straps 12a, 18a along the second side, the straps 12a, 18a, are pulled and releasably secured tightly about thefirst and second mattresses 26, 46. The excess length of strap 12a or 18a is then releasably secured with a suitable binding means 16 to the strap 12a, or 18a, if needed.

The mattress straps 12b, 18b are preferably releasably secured by additional fastening means 14 one side at a time. After releasably securing the straps 12b, 18b along the second side, the straps 12b, 18b are pulled and releasably securedtightly about the first and second box springs 24, 44. The excess length of strap 12b or 18b is then releasably secured with a suitable binding means 16 to strap 12b, or 18b.

The purpose of the straps 12a,b and 18a,b are to connect the mattresses 26, 46 and box springs 24, 44 so that they will not separate during use. Separation during use is the main reason that great discomfort occurs when people, who are stuckwith twin/single beds, but want to sleep together, are unsuccessful in creating one sleeping area by simply pushing their beds together.

Any variances in the size of the mattresses 26, 46 can be accommodated by adjusting the straps 12a,b and 18a,b, and excess strap can be held in place by the binding material 16. The binding/material 16 further serves as a second means to avoidslippage of the straps 12a,b and 18a,b during use.

When a bolster 70 is used, as shown in FIG. 6 the seam protector 10 is laid over the seam formed between the adjacent sides of the beds 20, 40, as previously disclosed. The bolster(s) 70 would then be placed at one end of the mattresses 32, 52or 34, 54, with the top portion of the bolster 70 in line with the top portion 36, 56 of the first and second beds 20, 40. The seam protector would be positioned over the bolster 70 so that the strap 12a or 18a would be positioned at about the midpointof the side of the bolster 70. Preferably, an indentation 72 is provided at the side of the bolster 70 to receive the strap 12a or 12b. The strap 12a or 18a would then be placed around the bolster 70 and secured about the first and second beds 20, 40,as previously noted.

When two twin/single beds are pushed together they form the approximate width of a king sized bed. Most often, the desire in pushing the beds together is for the purpose of people wishing to sleep together. However, sometimes the purpose isstrictly for want of more sleeping room. In this case, the user may also wish to extend the length of the beds 20, 40 with a bolster 70, to provide additional length similar to a king sized bed.

The straps 12a, 12b and 18a, 18 be may be rolled up into loops 76 and secured with a suitable strip 78, as shown in FIG. 7. The strip 78 may be releasably secured to itself about each rolled up strap 12a, 12b, 18a, with a snap, catch, hook andloop, or other known releasable securement means.

As shown in FIG. 4B, the mattress connecting apparatus may comprise a seam protector having first and second mattress straps 12a, 18a, without the use of first and second box springs straps 12b, 18b. Alternately, one mattress strap 12a may beadapted to extend entirely around the first and second beds, for securement by a first releasable securement means.

While a specific embodiment of the invention has been shown and described herein for purposes of illustration, the protection afforded by any patent which may issue upon this application is not strictly limited to the disclosed embodiment, butrather extends to all structures and arrangements which fairly fall within the scope of the claims which are appended hereto.
